SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 787,999, dated April25, 1905.

Application filed February 18, 1904. Serial No. 194,152.

T f/,ZZ whom ff may(fo/tecra: l bushing f/ being' provided with a screw-Be it known that I, HARRYJ. VALENTINE, a i threaded boss g2 and thelower bushing with 5o citizen ot' the United States, residing at Clcveasimilar boss la. iVithin the upper and lower land, in the county ofCuyahoga and State of knuckles t' j, respectively, of the intermediateOhio, have invented certain new and useful member or web a are plugs orbushings lmprovements in Spring-Hinges, of which the respectively.

The leaves c, provided j'. Each leaf c isprovided with an upper with the knuckles .r/ are in like mannerreknuckle and with a lower knuckle t, which intorced and ornamented bytransverse strips knuckles are substantially cylindrical and ret, whichare bent around both faces of each spectively receive plugs or bushingsg z, the of said leaves and formed into said knuckles,

the portions of the strips s s in contact with the said leaves beingsuitably secured thereto. It will be seen that each of the transversereinforcing-strips is made of substantially, if not of, the same widthfrom end to end and that the two side portions of each bent-up striptheonly portions besides the knucklestraddle the leaf transversely thereoffrom the knuckle and lie in substantially parallel planes IO with theleaf, so that the ends of the leaves are uncovered.

As is well known, in this class of hinges the lower ends of thetorsion-springs are anchored-that is to say, they are fixed against I5turning--while the upper ends thereof are turned by means ofcapstans-such as o, be fore mentioned-these capstans being provided witha series of sockets 02 to receive a securing-pin, such as p, whichprojects from 2O the capstan and engages with the corresponding leaf. Inthe present invention riveting of the bushing, plug, or core inside theknuckles j is dispensed with. Instead advantage is taken of the factthat by using a metallic 2 5 strip to form the knuckles 7' recesses,such as q, are left at each edge of the intermediate web or member ct,which recesses are located to one side of the knuckles. rIhe bushings orplugs Z are therefore formed irregular in contour or have a sideprojection or nose r, which sets into the recess q, thus preventing theturning of the said bushing or plug. The

lower ends of the torsion-springs being thus prevented from turning,tension may be ap- 3 5 plied to the springs by turning the capstans 0.When the door is opened in either direction, the appropriate leaf actson the straining or tension pin p, thus placing the spring under greatertension, the reaction of which is suflicient to close the door whenreleased.

I-Iaving thus described my invention and without limiting myself todetails, what I claim as newV therein, and desire to secure by LettersPatent, is;

l. In a spring-hingathe leaves, an intermediate member or web, andstrips, formed with knuckles and secured transversely thereon at somedistance from the ends of the said member, substantially as described.

2. In aspring-hinge, the combination of the intermediate member, leaves,transverse strips on the said member and leaves formed with cylindricalknuckles, and pintles passing through the knuckles, substantially asdescribed.

3. In a spring-hinge, the combination of a knuckle member, in which arecess is located at one side of a knuckle, a bushing or plugsubstantially filling said knuckle and of irregular shape to provide anose or projection 6C to engage said recess to prevent turning of thebushing, a spring connected at one end with said bushing, a leaf orsecond knuckle member, a pintle passing through the knuckles andbushing, said second knuckle mem- 6, ber being subjected to the actionof the other end of said spring, and a spring and pintle casing.

In testimony whereof I have signed this specification in the presence oftwo subscrib- 7 ing witnesses.

HARRY J. VALENTINE.
